No Neutron Star Companion To The Lowest Mass SDSS White Dwarf
Marcel Agueros, Craig Heinke, Fernando Camilo +6
SDSS J091709.55+463821.8 (hereafter J0917+4638) is the lowest surface gravity white dwarf (WD) currently known, with log g = 5.55 +/- 0.05 (M ~ 0.17 M_sun; Kilic et al. 2007a,b). S…
High-Redshift SDSS Quasars with Weak Emission Lines
Aleksandar M. Diamond-Stanic, Xiaohui Fan, W. N. Brandt +14
We identify a sample of 74 high-redshift quasars (z>3) with weak emission lines from the Fifth Data Release of the Sloan Digital Sky Survey and present infrared, optical, and radio…
Chandra Observations of the Highest Redshift Quasars from the Sloan Digital Sky Survey
Ohad Shemmer, W. N. Brandt, Donald P. Schneider +7
We present new Chandra observations of 21 z>4 quasars, including 11 sources at z>5. These observations double the number of X-ray detected quasars at z>5, allowing investigation of…
Magnetic White Dwarfs from the SDSS. The First Data Release
Gary D. Schmidt
Beyond its goals related to the extragalactic universe, the Sloan Digital Sky Survey (SDSS) is an effective tool for identifying stellar objects with unusual spectral energy distri…
Galaxy Clustering in Early SDSS Redshift Data
SDSS Collaboration, Idit Zehavi, Michael R. Blanton +4
We present the first measurements of clustering in the Sloan Digital Sky Survey (SDSS) galaxy redshift survey. Our sample consists of 29,300 galaxies with redshifts 5,700 km/s < cz…
The Probable Optical Counterpart of the Luminous X-ray Source in NGC 6441
Eric W. Deutsch, Scott F. Anderson, Bruce Margon +1
We report results from Hubble Space Telescope WFPC2 imaging of the field of the luminous, bursting X-ray source in the globular cluster NGC 6441. Although the X-ray position is kno…
An Ultraviolet-Excess Optical Candidate for the Luminous Globular Cluster X-ray Source in NGC1851
Eric W. Deutsch, Scott F. Anderson, Bruce Margon +1
The intense, bursting X-ray source in the globular cluster NGC 1851 was one of the first cluster sources discovered, but has remained optically unidentified for 25 years. We report…
Resolving the Helium Lyman- Forest: Mapping Intergalactic Gas and Ionizing Radiation at
Craig J. Hogan, Scott F. Anderson, Martin H. Rugers
We present a new, high resolution HST/GHRS spectrum of quasar Q0302-003, and use the HeII Lyman- absorption, together with a high resolution Keck spectrum of the HI Lyman- fo…
